rsync is an open source utility that provides fast incremental file transfer, freely available under the GNU General Public License and maintained by Andrew Tridgell. It uses the rsync algorithm to bring remote files into sync by sending just the differences across the link. Some features include updating whole directory trees and optionally preserving symbolic links, hard links, file ownership, permissions, devices and times.

SpeedCubeDB is a free online speedcubing algorithm and reconstruction database. It covers algorithms for 2x2 through 6x6 cubes as well as Square 1, Pyraminx, Megaminx, and Skewb. The site also lists practice tools including a scramble analyzer and cross trainer, and offers login for tracking progress.
Stan is software for Bayesian data analysis that combines statistical modeling capabilities with user-friendly interfaces and open-source development. Its probabilistic programming language supports applications from simple linear regression to multi-level models and time-series analysis. Interfaces exist for Python, Julia, R, and the Unix shell, usable on laptops, clusters, or in the cloud. Official documentation covers the language, inference algorithms, and built-in functions.
StudyForrest is a dataset collection built around the movie Forrest Gump, providing reproducible complex sensory input for brain research. It includes fMRI scans, structural brain scans, eye-tracking data and extensive annotations of the movie. The project offers reference datasets for benchmarking brain imaging algorithms and for studying cognition under natural stimulation.
SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists and researchers working with sound. It is free and open source software for Windows, MacOS and Linux. Its three main components are scsynth, a real-time audio engine implemented as a server; sclang, an interpreted programming language acting as a client; and scide, an editor for sclang.
Surprise is a Python scikit for building and analyzing recommender systems that deal with explicit rating data. It includes built-in datasets, prediction algorithms such as SVD and NMF, similarity measures, and cross-validation tools. The documentation states that Surprise does not support implicit ratings or content-based information.
GFPGAN is a face restoration algorithm for old photos or AI-generated faces, created by tencentarc and available on Replicate. The model runs on Nvidia L40S GPU hardware and costs approximately $0.0076 to run. It is also open source and can be run on a personal computer with Docker.
TeraCopy is a Windows utility that replaces Explorer's copy and move functions. It can verify copied files with checksum algorithms, skip problematic files instead of terminating a transfer, and wait for network or device reconnection. It supports task queuing, transfer history, and metadata configuration.
An online tool that calculates checksums of ASCII or Unicode text and of files up to 5MB, using a list of hash algorithms including MD5, SHA1, SHA256 and SHA512. It states that checksums are commonly used to verify data integrity, such as confirming a downloaded file is error-free.
Tidal Cycles is a free/open-source live coding environment for making algorithmic patterns, written in Haskell. It uses SuperCollider for synthesis and MIDI and includes notation for rhythmic sequences with patterning functions. By default sound is made with the SuperDirt synth/sampler, and other synths can be controlled with OSC or MIDI.
Tofu is an open-source two-factor authentication app for iOS. It generates one-time passwords using the HOTP and TOTP algorithms with 6 or 8 digits, requires no network connection, and stores account details in the iOS keychain. The source code is available on GitHub under the ISC license.
Toyota Technological Institute at Chicago is a philanthropically endowed computer science graduate institute. Its research areas include algorithms and complexity, computational biology, computer vision, machine learning, robotics, and speech and language. The institute offers a PhD program.
Trail Router is a running route planner. Its routing algorithm prefers paths through parks, forests or by water and avoids busy roads where possible. It can automatically plot a round-trip route of a desired distance or support manually created point-to-point routes, with preferences for nature, lit streets or fewer hills. Android and iPhone apps are available.
TridUI is a lightweight desktop application that provides a user-friendly interface for TrID, a tool for scanning and analyzing files. It uses a native Go implementation of the TrID file identification algorithm and runs on Windows, macOS and Linux. Users can drag and drop files to run local scans, and the app can download and update TrID definitions automatically.
